Abstract

A platen for use with an injection molding machine includes a body having an opening for receiving a ring protruding from a mold for aligning the body and the mold. The opening includes a tapered recess having a surface extending radially outward from the opening. The tapered recess defines opposed edges along an outer surface of the body, the opposed edges converging in a radially outward direction away from the opening.

First claim

The invention claimed is:

1. A platen for use with an injection molding machine comprising:
a body having an opening for receiving a ring protruding from a mold for aligning the body and the mold, the opening including a tapered recess having a surface extending radially outward in a vertical direction from at least one of an upper portion and a lower portion of the opening, the tapered recess defining opposed edges along an outer surface of the body;
wherein in response to the ring of the mold being positioned at least partially vertically above the opening or positioned at least partially beneath the opening and laterally aligned with the opening such that the ring is brought into contact with at least one of the opposed edges of the tapered recess and the surface of the tapered recess, and a continuous force applied to the mold toward the opening, and the ring being incrementally moved vertically toward the opening, at least one of the opposed edges and the surface of the tapered recess guiding the ring into engagement with the opening.

2. The platen of claim 1 , wherein the opposed edges of the tapered recess converging as the opposed edges extend toward a radially outward direction away from the opening.

3. The platen of claim 2 , wherein the opposed edges intersect at an end of the tapered recess away from the opening.

4. The platen of claim 1 , wherein the opposed edges do not intersect.

5. The platen of claim 1 , wherein the opposed edges are symmetric about an axis.

6. The platen of claim 1 , wherein the tapered recess has a curved surface.

7. The platen of claim 1 , wherein the tapered recess having a depth from the outer surface of the body, the depth decreasing in a radial direction away from the opening.

8. The platen of claim 7 , wherein the depth of the tapered recess decreasing at least partially linearly in the radial direction away from the opening.

9. The platen of claim 7 , wherein the depth of the tapered recess decreasing at least partially non-linearly in the radial direction away from the opening.

10. A platen for use with an injection molding machine comprising:
a body having an opening for receiving a ring protruding from a mold for aligning the body and the mold, the opening including a tapered recess having a surface extending radially outward from the opening;
wherein the tapered recess defining opposed edges along an outer surface of the body, the opposed edges converging in a radially outward direction away from the opening.

11. The platen of claim 10 , wherein the opposed edges intersect at an end of the tapered recess away from the opening.

12. The platen of claim 10 , wherein the opposed edges do not intersect.

13. The platen of claim 10 , wherein the opposed edges are symmetric about an axis.

14. The platen of claim 10 , wherein the tapered recess has a curved surface.

15. The platen of claim 10 , wherein the tapered recess having a depth from the outer surface of the body, the depth decreasing in a radial direction away from the opening.

16. The platen of claim 15 , wherein the depth of the tapered recess decreasing at least partially linearly in the radial direction away from the opening.

17. The platen of claim 15 , wherein the depth of the tapered recess decreasing at least partially non-linearly in the radial direction away from the opening.
